I will start off by saying I am a Surefire guy, I have owned the same L4 Lumamax for over four years now and carry it with me every single day, it has yet to let me down and still works as perfectly as the day I bought it. I only have two main gripes about it, first is the pocket clip, which has no grip whatsoever. I have almost lost my flashlight more than a few times (the worst is when getting out of a car and the seat belt grabs the light and pulls right out without you even knowing). The non-tight clip makes for easy removal, but also has the ability to fall out of your pocket without you having any idea it ever came out. The second gripe I have about my Surefire is that it is horribly inefficient. It gets extremely hot in only a few seconds and the thing sucks down batteries like crazy.So based on the two weaknesses of my Surefire I decided to venture out from the extremely expensive brand and seek out a less expensive, but still high quality, alternative. I researched various brands and lights and also watched several hours worth of Youtube videos on all the different lights out there, this ultimately led me to the 4Sevens Quark Tactical series.
What is it about the Quark Tactical series that I liked? For starters I am used to my simple easy to use Surefire, it has only one light output mode, has a forward clicky button (for momentary-on action) and its button protrudes quite a bit out the back which makes it very easy to use. Every other light I researched all had the awful multi-mode junk, where you have to cycle through 7 different output modes to reach the desired level... every time you you turn on the light!! How incredibly annoying and impractical! Not to mention every one of these other lights all had reverse clickys, no idea why anybody would ever desire a reverse clicky flashlight, but I will NEVER buy a flashlight without a forward clicky. And the fact that they all seemed to have reverse clicky buttons which were recessed made it even worse. I don't care at all about tail-standing, what I want is a nice fat button sticking out so I can easily and effortlessly turn on the light when I need it.
So the main draw the Quark tactical had was that it has a protruding forward clicky, it is more efficient, and you don't have to cycle through a bunch of output modes when you use the light. You can program 2 different modes which can be changed by simply turning the head of the light. So no matter what, and no matter how many times you click on and off, the light will ALWAYS be in the same mode until you physically turn the head to select a different output. This way you will have the confidence that when you use your light, you will KNOW what mode its going to be in. Whether that be for tactical reasons, survival reasons or utility reasons, this is a required feature for a flashlight with me. The other main plus for the Quark was that it has a tight pocket clip, which I needed because I was planning on carrying my light in a different spot on my person, and the Surefire, with its loose clip, would not have worked.
Pros:
Forward clicky - As mentioned previously, I prefer a forward clicky. The Quark tactical series may be one of the extremely few flashlights out there (aside from Surefire) to have a forward clicky, and this was one of the biggest selling points for me.
Protruding clicky - I like my clicky buttons to be protruding, as it makes it much easier and more practical to use in a momentary-on situation. I cannot stand recessed clicky buttons, especially reverse recessed clicky buttons!
Bright with lots of options! - One of the big pluses with this light is how bright it can get, at 205 lumens it is almost double the power of my 120 lumen Surefire. I tested it last night outside in pure darkness, and I was absolutely blown away at how much light was thrown into the yard! Even for a larger flashlight this would be extremely impressive, but you must remember that the Quark 123 is tiny, so that makes it much more insane! Not to mention I can choose between 5 brightness levels and 3 blinking modes. I have found that when the light is on high (at 85 lumens) it is close enough to the brightness of my surefire and works great for almost every situation. But if I want 22 lumens or even less, I can have it!
Amazing efficiency - As flashlight technology advances, they inevitably become more efficient. This light is no exception, and is amazing how long some of the modes can last on a single CR123 battery! My Surefire sucks down batteries, and it does it two at a time. On high mode with my Quark, at 85 lumens, the light output is close enough to my surefire and will last twice as long with half the battery capacity... now that is impressive!
Good weight - Not all of us want a featherweight knife or flashlight like Nutnfancy does, some of us actually like our knives and flashlights to have some heft to them. While this light is much lighter than my Surefire, it still has some weight to it when it is loaded. It weighs just slightly over 2oz, and feels good in the hand and pocket.
Good knurling - I think the knurling on this light is just right, not too much and not too little. Has enough so you can get a good purchase on the light, and it generally feels secure in your hands. If you have bigger hands, then the small size could be an issue, but for me it is just about right.
However, it is not all perfect. After receiving the light I see several things which could be vastly improved upon, and I will list them below in hopes someday a flashlight company (like 4Sevens) could make such changes to their lights.
Cons/needed changes:
Button needs more protrusion - What I mean by this is, that while it is nice the button is protruding out the back, it needs to be longer. My Surefire button protrudes out quite far and is rounded nicely, this makes using the momentary-on feature effortless and easy. With my SF I can easily use any part of my thumb to turn the light on. With my Quark Tactical 123, you have to press down kind of hard and the button doesn't have much 'travel' before it actually clicks on. So what this means is that the only effective way to use the momentary-on with the Quark is with the very tip of your thumb. And since it has very little travel and is tighter, this makes holding the momentary-on more of a 'chore' than with my SF.
Should have 3 programmable modes - Right now there is only two modes you can program with the light, and while this is pretty nice, I think often times people would like to have a third option without having to go through the procedure of reprogramming again. For me the two modes I use are MAX and High, but it would be nice if I could program Max, High, and Medium to be available just by turning the head.
Head turning needs to 'click' - One problem with the two modes on the head, is that when the light is off you really can't tell if you are in the first mode, or second mode. If you crank the head way over so the head is at its tightest spot, you will obviously know you are on the first mode, but getting to the second mode with the light off is mostly a guessing game. If the head made little 'clicks' when it got to another mode, that would be significantly better for an almost infinite number of reasons. And if someday they do decide to have 3 modes programmed on the head, then this feature would be a must-have. One other solution is to have little circles notched (or laser engraved) into the side of the light, so you can see what mode its in without having to turn it on.
Clip position could be improved - Right now, at least on the small Quark 123 Tactical version, the clip is permanently mounted to the head of the light (about mid-way on the body). I really don't have a problem with the the light being bezel up when in pocket, but they should mount the clip up much future on the head. There is just too much of the light sticking out, and I would much prefer a deeper pocket carry. Cause the more the light sticks out, the more chances it may fall out, get accidentally ripped out, get damaged, or even give somebody a opportunity to pick-pocket your light. This may not be an issue too much with the Quark 123x2 tactical because it is longer, but this Quark 123 is very short, and right now almost 50% of the light is above the rim of my pocket.
Clip is too tight - Yes granted I am used to my loose Surefire clip, but the Quark 123 clip is extremely tight! Just to get it in my pocket I often have to use two hands and takes several seconds to mount it in, and getting it out is a serious chore as well. The clip could definitely be loosened a little and perhaps redesigned so that it can be looser but still provide enough grip so that it won't inadvertently fall out of a pocket. The tightness of the clip makes it inconvenient to use the light, which should not be the case with a tactical/utility/survivor flashlight. It should be able to slip in/out of a pocket easily with one hand yet be tight enough to resist falling out. As Nutnfancy would put it, this clip has some serious Wizard of Oz issues!
Clip gets in the way - Yup, another clip one. This could go hand-in-hand with either of my previous clip topics (about its position and tightness). When programming the light the clip makes it very difficult to turn the light rapidly 4 times, as the clip is attached to the head, so it turns when you turn the head. This light is small, and the middle section of the light, which is only about 1/2" wide, is the part you have to grab in order to turn the head to program it or to switch modes. If you grab the back of the light and turn, you may just end up unscrewing the battery cap and not the head. Also the clip gets in the way when you are trying to screw/unscrew the battery cap (the button end). In fact in order to put the end back on, you have to lift up the clip (which is extremely strong and hard to pivot with one finger) then quickly screw on the cap while simultaneously lifting up the clip with your other hand to get it out of the way. It is possible to jam the end-cap onto the threads and under the clip, but it just doesn't seem right.
Preflash - If you have done any searching on this light, you will have heard about the notorious preflash. Well I will say that while there is preflash on my light, its really not that bad at all and only happens when I do things in a certain order. For example, if I turn the light on and put it in its MAX mode, turn it off, turn the head to the lower mode, then turn it on... I will get preflash. But after that point it never does it again. If I turn on my light in max mode, switch to a lower mode, turn it off and turn it on... I get no preflash. The only time it happens is when I start with a higher mode, and turn the head while the light is off and turn it back on. Still something 4Sevens needs to fix, but it is not too bad on my light.
Inductor whine - I may change this when I get my replacement light, but as it stands now my light makes this hissing high-pitched noise when its in its MAX mode (sometimes in high too). It is very annoying and makes it sound like the flashlight is going to explode or something. Oddly enough using higher voltage batteries seems to have helped, I only get a slight whine when using rechargeable li-ion batteries, whereas when I am using primary lithium batteries it is pretty loud. I have read several posts from people in forums quoting 4Sevens saying that this is not considered a defect, well I don't know if it is one or not, but it is unacceptable. My Surefire NEVER makes any hissing or high pitched noises, and no flashlight should EVER make such noises.
Needs more flood - My Surefire has superb flooding ability, and this makes using it for close-up tasks ideal (which is 99% of the things I use flashlights for). The Quark 123 Tactical has decent flood, but its more primed for a long-distance spot, so for close up utility tasks it is not as useful as my Surefire. Sure it still works great, its just not as good as it could be. For a small light like this, which is going to be mostly used by people for close-up tasks, it should have had better flood.
Other than the things I would like to see improved, it is still a great little light. It is amazing how much light it can output, and the fact it is more efficient is great, which means less batteries to buy. I will update this review as necessary, and when I get my replacement light I will see if it has inductor whine as well. If it does, I will likely lower the score down to 3 stars, because that is a unacceptable QC issue IMO. I can deal with the preflash, but I drawn the line at a hissing flashlight.
But all-in-all if 4Sevens made the adjustments as I have stated in this review, the Quark Tactical series would be the perfect light, and no doubt would be a true Surefire killer.
